Adhesive droplets made from plant-derived oils for control of western flower thrips

Arthropod pests cause significant problems in agricultural crops all around the world. As chemical pesticide use becomes less desired, there is a need for alternative methods of pest control. Inspired by the natural adhesiveness of arthropod trapping plants, we examined the effectiveness of adhesive droplets made from oxidised and cross-linked plant-derived oils for control of western flower thrips. Two filter paper droplet adhesiveness assays and three detached chrysanthemum leaf assays were carried out to test efficacy against thrips. Suspensions containing adhesive droplets and other constituents were applied to filter papers and leaves via spraying or dipping. On filter papers, droplets made from oxidised rice germ oil (RGO) of different sizes caught 40–93% of thrips. Droplets made of a mixture of sunflower, olive, and linseed oil (MIX) caught up to 94% of thrips. Likewise, adhesive droplet-treated filter papers showed higher thrips mortality than untreated or control solution-treat..., Data type: experimental data, various measurements of Insect-bioassays performed in Petri-dishes.
Aim: to assess if adhesive droplets made from natural materials could trap thrips (tiny insects and a major pest)
Methodolgy:
Exp1: filter papers were sprayed with different sizes (R180, R360, R720) adhesive droplets made from oxidized rice germ oil. Thrips were added and at several timepoints the number of thrips stuck in the droplets was counted.
Exp2: Same as experiment 1, but with 2 different droplet prototypes (Mix, made from a mixture of vegetable oils) (RGO360-90, same as RGO360, but temperature used during oxidation set at 90C)
Exp3: same as experiment 1, but using detached chrysanthemum leaves that are placed in agar. only a single measurement after 5 days. damage to the leaf by thrips feeding was also measured, as well as reproduction of the thrips.
Exp4: same type of detached leaf assay as Exp3, but using the samples Mix and RGO360-90), this time particle coverage was also measur..., , # Adhesive droplets made from plant-derived oils for control of western flower thrips
